VSerial No. 497,159.

This invention relates to hinge connections for members to'be 'pivotally connectedA to other members and is particularly adapted in mounting seats and covers therefor onwater closet hoppers. i Y

The invention consists of novel means for attaching the hinge plates to the seats and covers, the object being to rigidly-secure these plates in position without the use of screws 0r similar elements.l 1 Y This object is attained by the construction shown and described in the accompanying drawings.

Forthe purpose of illustrating theinvention, one preferred. form thereof is illustrated in the drawings, this form having been found to give satisfactory and reliable results, although it is'to be understood that the various instrumentalities of which the'invention consists can be variously arranged and organized,` and the invention is not'limited to the precise arrangement and organiza: tion of these instrumentalities as herein shown and described except as required b thescope of the appended claims Of the drawings: Figure 1 represents a plan of a water closet hopper having a seat and coverl mounted thereon by hinge connections embodying the principles of the present invention.l i Figure 2 represents aside elevation ofthe same.

Figure 3 represents an enlarged transverse section of the same on line 3, 3, on Fig. 1 and showing the means for securingfthe hinge plates to the cover.

Figure 7 represents a side elevation of said seat and one of its hinge connections showing the seat down. A

Figure 8 represents a side elevation of same Figure 9 represents an elevation of oneof the end plates of one of theseat hinge connections, and

Figure 10 represents an inverted plan'of same. i

` Similar characters indicateV 'like parts throughout the several `figures of the draw inge Y l f In the drawings, 10 is a portion of a water. closet hopper having la flange 11 to which the posts 12 are secured in theusu'alV manner by nuts 13 threaded to shanls lliextending through the flange 11. l

The upper end of each post 12 is provided with an opening 14 throughwhich extends a cylindrical shank 15 formed upon the end plate 16,and projecting into a cylindrical hole 17 in a rearward extension 18 Aforming part of a seat 19. i

Each post 12 is provided with a stopl shoulder 20 against which the ears 21 projecting inwardly lfrom the plates 16 are adapted to rest to limit the rearward movement of the end plates 16 when the cover 22 supported by said plates 16 is moved into its raised position. i v K VThis cover 22is provided with a rearward extension 23 having parallel end Vfaces against which the end plates 116 are adapted to abut.

These end plates 16 are provided with one or more lugs 24 which are adapted to be forced into the ends of the extension '23 of the cover 22 or be disposed in holes previously formed in said-cover. f

EachV plate 16. is also 'provided with a threaded boss 25 to which is threaded a metal rod 26 disposed within and accurately fitting a cylindrical hole 27 extending transversely of the extension 23 from end to end. g

The inner ends of theoppositely disposed rods 26 are tapered as at 28 and meet as shown in Fig. 3 of the drawings,the'hole 27 serving as a; guide so that the tapered ends will always meet accurately with said hole.`

The hole 27 is first formed in theeztension 23 and then the rods v26 mounted on the end plates 16 are forcedinto thehole under pressure, the lugs 24 beingV pressed into the wood or other material from which the cover is constructed.

At the same time these rods 26 are being forced inwardly with their ends 28 contacting, an electric current is passed through the rods causing the inner ends 28 thereof to be welded together so that the end plates 16 are permanently secured in position and cannot be separated.

l/Vhen the rods 26 are being inserted into the hole 27 of the extension 23 of the cover, the cylindrical shanks 15 are being forced into the rear extension 18 of the seat 19.

When the ends 28 of the rods 26 are thus connected together, it is impossible for the cylindrical shanks 15 forming a pivot for the seat 19 to be displaced from said seat.

By this construction the use of screws and similar instrumentalities is dispensed with and the outer faces of the end plates 16 are smooth and unbroken, thus leaving no depressions in which foreign substances may lodge.

Owing to the lugs 24 extending into the ends of` the extension 23, the seat 22 will always move with the end plates 16 when said end plates are moved about the axes of the cylindrical Shanks 15 extending through the bearings 14 in the post 12.

The rearward movement of the cover 22 when in its raised position is limited by the ears 21 contacting with the shoulders 20 formed upon the posts 12.

By this construction of hinge connection, said hinge connections may be secured to the cover or seat after said cover and seat has been enveloped with sheets of Celluloid or other material without dangery of injury thereto.

In some cases it is desirable to dispense with the cover and pivot the seat 18 directly onto the post 12.

In this case, the end plates 29 differ in shape from the end plates 16 but have inwardly eX- tending ears 30 adapted to coact with shoulders 31 on the post 12 to limit the rear movement of the seat 19 when in its raised position,

J as shown in Fig. 8.

The end plates 29 have projecting from their inner faces threaded bosses 32 which extend through bearings 33 in the posts 12.

Threaded to these bosses 32 are the rods 34, the inner ends 35 of which contact within the hole 36 formed in the extension 18 of the seat 19, all as shown in Fig. 6 of the drawings.

The bosses 32 have oppositely disposed prongs 37 formed on the inner end thereof which are adapted to be forced into the material of which the seat is formed, thereby providing means whereby the seat and end plates 29 will always move together about the axes of the rods 34.

When the bosses 32 have been disposed within the bearings 33 of the posts 12 and the rods 34 threaded to these bosses, the rods 34 are inserted into the hole 36 and under great pressure are forced towards each other until the ends 35 thereof contact and during this operation an electric current is transmitted through the rods causing the contacting ends 35 to be welded together.

The Shanks 14 may then be inserted through the bearings therefor in the flange 11 and the nuts 13 threaded thereto.

When the rods 35 have once been secured together in the manner described, the end plates 29 are permanently retained in position upon the post 12 and cannot be separated therefrom.

When the seat 19 is moved into its raised position as indicated in F ig. 8, the lugs 30 will rest upon the shoulders 31 and limit the rear movement of said seat.

By mounting the seat and cover on a water closet hopper by such hinge connections as are herein shown and described, a perfectly sanitary construction is provided which has great strength and the elements of which are permanently retained in position.

By this construction the use of all screws and similar instrumentalities is entirely dispensed with, which is of considerable advantage as such elements are liable to become loose in use and permit the various elements of the hinge connection to get out of position.

While the use of lugs 24 on the plates 16 is desired, it is obvious that other means may be provided for locking the end plates 16 to the end walls of the extension 23 in order that the end plates may be flrmly secured to said extension 23 so that said plates 16 and seat 22 lwill always be moved together about the axes of the pivot members 15.

lhile the end plates 16 are shown with threaded bosses 25 having the rods 26 secured thereto, it is obvious that these rods could be formed integral with said end plates if desired.

The end plates 16 are shown attached to the Water closet seats and covers therefor, but it is self-evident that same method of attaching metal parts toy wooden members is adapted for use in many other similar operations other than seats or covers.

It is believed that the operation and many advantages of the invention will be understood without further description.
